## Markdown — for all written work in your repo

Most of your SAT documentation (`prepared-data.md`, `data-collection-plan.md`, lesson logs, evaluation matrices) is written in **Markdown**. It's plain text with light formatting characters — fast to type, easy to read in any editor, and renders cleanly on GitHub.
